So your lawyer messed up your first case and you decided to hire him for a second one? I'll let that one sink in for a bit, but to answer your question, yes you can sue your lawyer for negligence (malpractice) once something actually occurs that damages you.
At the moment, however, as I understand your facts, you need to respond to the pending Motion to Dismiss your case. If your lawyer is not properly handling your case (and it sure sounds from the way you describe it that he is NOT), then you need to hire a new attorney. Today. And have them respond to the Motion to Dismiss and fix whatever issues need to be fixed. Then you can seek to have your present attorney disgorge fees to cover the new attorney's fees and maybe you won't need to file a malpractice lawsuit.
Need assistance hiring a new attorney, see my article on what to look for when hiring a bankruptcy lawyer.
You can also contact the state bar to report the attorney, but that isn't going to fix your immediate problem.
